Ask HN: Side business is flush with 40k, what now?

Looking for advise on what I should do with some of my cash from my business. I have a couple options:

Hire a developer ( part time) to help me build some some product offerings

Use some of it to hire sales person with commission mix

Invest a portion of it

Find a revenu generting asset or small business that compliments my current buisiness.

Other options?

I never thought I would make this money from my side business in the first place. I'm at a point where If I use these funds correctly I can break free from my 9 - 5.

Thank you in advance.
